I sent a suggestion for a show like this a few years ago to Food Network. It should be great. My favorites include:
WDW has so many great places. I think California Grill is my favorite. The sushi there is excellent. I have only eaten at O'hana once, but I thought it was really good. I've always enjoyed the thick Rice Krispie Treats sold on Main Street. San Angel Inn has the best atmosphere of any park restaurant. Someday I hope to dine at Victoria & Albert's which I hear is the pinnacle of dining.
BGE has great food overall. I especially enjoy Das Festhaus and the Italian place.
Kennywood, Knoebel's, & Holiday World can't be beat for value.
Of course the Potato Patch fries are famous at Kennywood, but I have had other great meals all around the park.
The deep fried pierogies at Knoebel's are the best snacking food at any park. The pizza was also excellent.
The fudge at Holiday World is the best fudge anywhere.
I had some great tacos at Indiana Beach.
There are others, but these stand out to me.
